摘要：

The proton magnetic relaxation rate 1/T1 for labelled methanols CH3OD and CD3OH in mixtures with (CD3)2SO has been measured as a function of temperature and frequency. In the low-temperature region, maxima and a strong frequency dependence of 1 T1 were found. The results were evaluated on the basis of intra- and intramolecular relaxation theories. The intermolecular relaxation rate, to which this study is mainly devoted, is found to be markedly smaller than predicted by the theory. Some information about the motion of molecular groups in methanol is obtained. © 1979.
